P1: Transverse axes

4.4 Supplementary conditions

Reference is made exclusively to the transverse axis of the channel.
Axis-specific diameter programming for several transverse axes in one channel
Note
The additionally specified axis must be activated via MD30460
$MA_BASE_FUNCTION_MASK with bit 2 = 1.
The axis specified must be a known axis in the channel. Geometry, channel or machine axes
are permitted.
Programming is not permitted in synchronized actions.
The following axis-specific modal statements can be programmed several times in a part
program block:
● DIAMONA[<Axis>]: Diameter programming for G90, G91, AC and IC ON
● DIAMOFA[<Axis>]: Diameter programming OFF, in other words, radius programming ON
● DIAM90A[<Axis>]: Diameter or radius programming depending on the reference mode:
– Diameter programming ON in connection with absolute dimensioning G90 and AC
– Radius programming ON in connection with incremental dimensioning G91 and IC
● DIACYCOFA[Axis]: Radius programming for G90 and G91 ON, for the HMI, the last
active G command of this group remains active
● DIAMCHANA[Axis]: Acceptance of diameter programming channel status
● DIAMCHAN: All axes with MD30460, bit 2 = 1 accept the diameter programming channel
status
Axis-specific modal statements have priority over the channel setting.
4.4 Supplementary conditions
Axis interchange
Due to a GET request from the parts program, the diameter programming status for an
additional transverse axis is accepted in the new channel during axis replacement
using RELEASE[<Axis>].
Axis interchange in synchronized actions
For axis replacement in synchronized actions, a transverse axis takes the status of the axis-
specific diameter programming with it into the new channel if:
● with MD30460, bit 2 = 1 axis-specific diameter programming is permitted for the transverse
axis.
● the transverse axis is not subordinated to the channel-specific diameter programming in the
releasing channel.
The active dimension can be queried via the system variable $AA_DIAM_STAT[<Axis>].
